It is $84.6. You multiply 1.6 by 13 which equals $20.8. Then you multiply 3.1 by 14 which equals $43.4. Then you multiply 1.2 by 17 which equals $20.4. Add them together and you get $84.6.
Hope this helps:)<span />
I(interest)=P(princple)R(rate)T(time)
I=420*.07*1=$29.4
A is correct.
Peace.
10x^2 - 36y^2 = 100
10x^2 = 36y^2 + 100
x^2 = (36/10)y^2 + 100/10
x^2 = (18/5)y^2 + 10 <== here ya go
10 percent of 6000 is 600
So the midpoint formula is 
. Using our information, our two equations are going to be
and 
.
Starting with the x-coordinate, multiply both sides by 2: 
Next, add both sides by 4 and your answer will be 
Next with the y-coordinate, its going to be pretty much the same process:
Putting everything together, our other endpoint is (4,-15).
